Kaito Kirishima witnesses a blue light speeding across the sky while testing his camera on a bridge one summer night, only to be blown from the railing seconds later. A hand reaches down to grasp ahold of his own just before he is about to pass out. Kaito wakes up the next morning dazed and disoriented, unsure how he got up back in his own room with no visible injuries and no memories of the night before. Kaito and his pals discuss what to do with his camera as they go about their daily lives, eventually choosing to produce a film with it over the summer holiday. Tetsurou Ishigaki, Kaito's buddy, notices Kaito's interest in the new upperclassmen Ichika Takatsuki and resolves to intervene.
